"Cesar came to consult on my leaking water heater, was super friendly and gave me a few options to choose from. Since my issue was a bit urgent, they were able to source a 75 gal water heater and by the afternoon they were able to start installation. Vincent came to do the installation and he was super friendly as well. He took care to dry up any water spillage, and tidied up and took time to answer my questions before leaving. Thanks to those two who love and take pride in their work."

"They did a number of things. Braced and restrapped water heater and ran copper line for pressure relief to outside. Unclogged master toilet and reseated. Bolted down second toilet. Reconnected clothes dryer vent. Repaired air gap/garbage disposal and drain line under kitchen sink, crawled under house and remove galvanized pipe straps and replaced with nylon pipe clamps. I was a contractor and used to do this work, o an very critical. They did an outstanding job. Went the extra mile several times. I was expecting a bill for a higher amount but they stuck with their estimate. I recommend them highly and would use them again!!"

"We had a backup in the kitchen sink that needed to be cleared up. Robert assessed the issue, and gave a more than fair quote. He even suggested , if need be, he'd crawl under the house and find the issue. I appreciated the obvious fact Robert wanted to make sure he left with a happy customer. He repaired and we are happy =) 5 STARS !!!!! "

"Very reasonable quote, great job with a father-son team. They did an excellent job installing my new water heater. Close attention to detail. No issues, no hassles, happy consumer! Compared to some other bait and switch contractors that quoted 2-3 times the price, Maverick was a blessing. Thanks a lot Maverick."

"The crew from Albert Nahman did a great job from start to finish. The project was to replace the original ductwork in our 60 year old house. Tom provided excellent advice for the estimate then Bryan’s crew did the job, 2 days, within a week of my acceptance of the proposal. Great work."

FAQs for water heater repair or service projects in San Mateo, CA

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
